3D printing filament Fiberlogy PCTG 1.75 mm 0.75 kg — Pure Transparent

Fiberlogy PCTG 1.75 mm 0.75 kg — Pure Transparent is a copolyester filament designed for FDM/FFF 3D printers that accept 1.75 mm material. The transparent spool delivers good optical clarity and consistent filament diameter for visual parts, prototypes and functional components where visibility of internal features or a clear finish is desired. Made from PCTG, the filament balances impact resistance and dimensional stability while offering improved chemical resistance compared with common PETG variants.

Advantages

The filament combines transparency with reliable printing behavior, providing stable extrusion and reduced risk of clogging on well-calibrated hotends. Its chemical resistance and toughness make it suitable for parts that require washability or contact with mild solvents. Dimensional stability and layer adhesion help produce precise prototypes and functional prints with clear surface finish and low warping on correctly tuned printers.

Suitable for

• Transparent prototypes and display parts
• Functional components requiring impact resistance
• Visual enclosures and housings where internal visibility is needed
• Educational models and demonstrators
• Low- to medium-temperature mechanical parts

How to use

Load the 1.75 mm Fiberlogy PCTG filament into a compatible FDM/FFF printer following the printer manufacturer's filament loading procedure. Use a clean, dry feed path and ensure the filament is free of dust or moisture before printing; drying prior to use may improve results if moisture absorption is suspected. Recommended printing settings typically include a heated bed and a hotend temperature appropriate for copolyester materials; fine-tune extrusion multiplier, print speed and cooling to achieve optimal clarity and layer adhesion for your specific printer and part geometry.

Usage recommendations

For best optical and mechanical results, print with moderate speeds, a nozzle temperature suited to PCTG, and minimal part cooling during early layers. Store the filament in a dry, sealed container with desiccant to preserve transparency and printing performance over time.
